Abstract
BACKGROUND Very few data have been published on the use of subcutaneous implantable cardioverter-defibrillators (S-ICDs) in patients with congenital heart disease (CHD). OBJECTIVES The aim of this study was to analyze outcomes associated with S-ICDs in patients with CHD. METHODS This nationwide French cohort including all patients with an S-ICD was initiated in 2020 by the French Institute of Health and Medical Research. Characteristics at implantation and outcomes were analyzed in patients with CHD. RESULTS From October 12, 2012, to December 31, 2019, among 4,924 patients receiving an S-ICD implant in 150 centers, 101 (2.1%) had CHD. Tetralogy of Fallot, univentricular heart, and dextro-transposition of the great arteries represented almost one-half of the population. Patients with CHD were significantly younger (age 37.1 ± 15.4 years vs 50.1 ± 14.9 years; P < 0.001), more frequently female (37.6% vs 23.0%; P < 0.001), more likely to receive an S-ICD for secondary prevention (72.3% vs 35.9%; P < 0.001), and less likely to have severe systolic dysfunction of the systemic ventricle (28.1% vs 53.1%; P < 0.001). Over a mean follow-up period of 1.9 years, 16 (15.8%) patients with CHD received at least 1 appropriate shock, with all shocks successfully terminating the ventricular arrhythmia. The crude risk of appropriate S-ICD shock was twice as high in patients with CHD compared with non-CHD patients (annual incidences of 9.0% vs 4.4%; HR: 2.1; 95% CI: 1.3-3.4); however, this association was no longer significant after propensity matching (especially considering S-ICD indication, P = 0.12). The burden of all complications (HR: 1.2; 95% CI: 0.7-2.1; P = 0.4) and inappropriate shocks (HR: 0.9; 95% CI: 0.4-2.0; P = 0.9) was comparable in both groups. CONCLUSIONS In this nationwide study, patients with CHD represented 2% of all S-ICD implantations. Our findings emphasize the effectiveness and safety of S-ICD in this particularly high-risk population. (S-ICD French Cohort Study [HONEST]; NCT05302115).

Abstract
Cancer-associated mesothelial cells (CAMCs) in the tumor microenvironment are thought to promote growth and immune evasion. We find that, in mouse and human ovarian tumors, cancer cells express anti-Müllerian hormone (AMH) while CAMCs express its receptor AMHR2, suggesting a paracrine axis. Factors secreted by cancer cells induce AMHR2 expression during their reprogramming into CAMCs in mouse and human in vitro models. Overexpression of AMHR2 in the Met5a mesothelial cell line is sufficient to induce expression of immunosuppressive cytokines and growth factors that stimulate ovarian cancer cell growth in an AMH-dependent way. Finally, syngeneic cancer cells implanted in transgenic mice with Amhr2-/- CAMCs grow significantly slower than in wild-type hosts. The cytokine profile of Amhr2-/- tumor-bearing mice is altered and their tumors express less immune checkpoint markers programmed-cell-death 1 (PD1) and cytotoxic T lymphocyte-associated protein 4 (CTLA4). Taken together, these data suggest that the AMH/AMHR2 axis plays a critical role in regulating the pro-tumoral function of CAMCs in ovarian cancer.

Abstract
Magnetic resonance imaging (MRI) has become the reference imaging for the management of a large number of diseases. The number of MR examinations increases every year, simultaneously with the number of patients receiving a cardiac electronic implantable device (CEID). A CEID was considered an absolute contraindication for MRI for years. The progressive replacement of conventional pacemakers and defibrillators by MR-conditional CEIDs and recent data on the safety of MRI in patients with "MR-nonconditional" CEIDs have progressively increased the demand for MRI in patients with a CEID. However, some risks are associated with MRI in CEID carriers, even with "MR-conditional" devices because these devices are not "MR-safe". A specific programing of the device in "MR-mode" and monitoring patients during MRI remain mandatory for all patients with a CEID. A standardized patient workflow based on an institutional protocol should be established in each institution performing such examinations. This joint position paper of the Working Group of Pacing and Electrophysiology of the French Society of Cardiology and the Société française d'imagerie cardiaque et vasculaire diagnostique et interventionnelle (SFICV) describes the effect and risks associated with MRI in CEID carriers. We propose recommendations for patient workflow and monitoring and CEID programming in MR-conditional, "MR-conditional nonguaranteed" and MR-nonconditional devices.

Abstract
The introduction of a new technology always raises questions about its place compared with the reference technology. The use of an implantable cardioverter defibrillator to prevent sudden cardiac death is now a widely proven technique, with a clear statement of its indication in the guidelines. More recently, a subcutaneous implantable cardioverter defibrillator has been introduced, and appears to be an attractive technique as it removes the need to implant a lead inside the right ventricle to treat the patient, which should dramatically decrease the risk of complications over time. Currently, only one model of subcutaneous implantable cardioverter defibrillator is available on the market; its indications are the same as for transvenous implantable cardioverter defibrillators, except for patients who need stimulation because of conduction disorders or ventricular tachycardias that can potentially be treated effectively by antitachycardia pacing. The different technical characteristics of transvenous versus subcutaneous implantable cardioverter defibrillators therefore raise the question of which to choose in different clinical settings. The experts who participated in the preparation of this manuscript had three meetings, organized by the company Boston Scientific. Each expert prepared the draft of a section corresponding to a clinical situation. The choice between transvenous versus subcutaneous implantable cardioverter defibrillator was then voted on by all the experts. The results of the votes are presented in this manuscript, as it seemed important to us to show the disparities of opinion that can exist in certain situations. The votes were cast independently and anonymously.

Abstract
Aims The choice of resynchronization therapy between with (CRT-D) and without (CRT-P) a defibrillator remains a contentious issue. Cause-of-death analysis among CRT-P, compared with CRT-D, patients could help evaluate the extent to which CRT-P patients would have additionally benefited from a defibrillator in a daily clinical practice. Methods and results A total of 1705 consecutive patients implanted with a CRT (CRT-P: 535 and CRT-D: 1170) between 2008 and 2010 were enrolled in CeRtiTuDe, a multicentric prospective follow-up cohort study, with specific adjudication for causes of death at 2 years. Patients with CRT-P compared with CRT-D were older (P < 0.0001), less often male (P < 0.0001), more symptomatic (P = 0.0005), with less coronary artery disease (P = 0.003), wider QRS (P = 0.002), more atrial fibrillation (P < 0.0001), and more co-morbidities (P = 0.04). At 2-year follow-up, the annual overall mortality rate was 83.80 [95% confidence interval (CI) 73.41–94.19] per 1000 person-years. The crude mortality rate among CRT-P patients was double compared with CRT-D (relative risk 2.01, 95% CI 1.56–2.58). In a Cox proportional hazards regression analysis, CRT-P remained associated with increased mortality (hazard ratio 1.54, 95% CI 1.07–2.21, P = 0.0209), although other potential confounders may persist. By cause-of-death analysis, 95% of the excess mortality among CRT-P subjects was related to an increase in non-sudden death. Conclusion When compared with CRT-D patients, excess mortality in CRT-P recipients was mainly due to non-sudden death. Our findings suggest that CRT-P patients, as currently selected in routine clinical practice, would not potentially benefit with the addition of a defibrillator.

Abstract
The patient population benefitting from cardiac implantable electronic devices (CIEDs) is increasing. This study introduces a device annotation method that supports the consistent description of the functional attributes of cardiac devices and evaluates how this method can detect device changes from a CIED registry. We designed the Cardiac Device Ontology, an ontology of CIEDs and device functions. We annotated 146 cardiac devices with this ontology and used it to detect therapy changes with respect to atrioventricular pacing, cardiac resynchronization therapy, and defibrillation capability in a French national registry of patients with implants (STIDEFIX). We then analyzed a set of 6905 device replacements from the STIDEFIX registry. Ontology-based identification of therapy changes (upgraded, downgraded, or similar) was accurate (6905 cases) and performed better than straightforward analysis of the registry codes (F-measure 1.00 versus 0.75 to 0.97). This study demonstrates the feasibility and effectiveness of ontology-based functional annotation of devices in the cardiac domain. Such annotation allowed a better description and in-depth analysis of STIDEFIX. This method was useful for the automatic detection of therapy changes and may be reused for analyzing data from other device registries.

Abstract
Early recovery after surgery provides patients with all means to counteract or minimize the deleterious effects of surgery. This concept is suitable for a surgical procedure (e.g., colorectal surgery) and comes in the form of a clinical pathway that covers three periods (pre-, intra- and postoperative). The purpose of this Expert panel guideline is firstly to assess the impact of each parameter usually included in the rehabilitation programs on 6 foreseeable consequences of colorectal surgery: surgical stress, postoperative ileus, water and energy imbalance, postoperative immobility, sleep alterations and postoperative complications; secondly, to validate the usefulness of each as criteria of efficiency criteria for success of rehabilitation programs. Two main criteria were selected to evaluate the impact of each parameter: the length of stay and frequency of postoperative complications. Lack of information in the literature forced experts to assess some parameters with criteria (duration of postoperative ileus or quality of analgesia) that mainly surrogate a positive impact for the implementation of an early recovery program. After literature analysis, 19 parameters were identified as potentially interfering with at least one of the foreseeable consequences of colorectal surgery. GRADE® methodology was applied to determine a level of evidence and strength of recommendation. After synthesis of the work of experts using GRADE® method on 19 parameters, 35 recommendations were produced by the organizing committee. The recommendations were submitted and amended by a group of reviewers. After three rounds of Delphi quotes, strong agreement was obtained for 28 recommendations (80%) and weak agreement for seven recommendations. A consensus was reached among anesthesiologists and surgeons on a number of approaches that are likely not sufficiently applied for rehabilitation programs in colorectal surgery such as: preoperative intake of carbohydrates; intraoperative hemodynamic optimization; oral feeding resume before ha24; gum chewing after surgery; patient out of bed and walking at D1. The panel also clarified the value and place of such approaches such as: patient information; preoperative immunonutrition; laparoscopic surgery; antibiotic prophylaxis; prevention of hypothermia; systematic prevention of nausea and vomiting; morphine-sparing analgesic techniques; indications and techniques for bladder catheterization. The panel also confirmed the futility of approaches such as: bowel preparation for colon surgery; maintain of the nasogastric tube; surgical drainage for colonic surgery.

Abstract
A 61-year-old man has been implanted with a Ventritex Profile MD V-186 HV3 ICD for ischemic cardiomyopathy with sustained inducible VT. Three years later, this patient received several inappropriate shocks during the device's interrogation. These shocks provoked ventricular fibrillation. They were caused by a failing soldering between the system random accessory memory (SRAM) module and the hybrid circuit of the device. The device was explanted in emergency.

Abstract
Background To analyze the in-hospital complication rate in women suffering from non-ST elevation myocardial infarction treated with percutaneous coronary intervention (PCI) compared to men. Methods The files of 479 consecutive patients (133 women and 346 men) suffering from a Non STEMI (Non ST-segment elevation myocardial infarction) between the January 1st 2006 and March 21st 2009 were retrospectively analyzed with special attention to every single complication occurring during hospital stay. Data were analyzed using nonparametric tests and are reported as median unless otherwise specified. A p value < .05 was considered significant. Results As compared to men, women were significantly older (75.8 vs. 65.2 years; p < .005). All cardiovascular risk factors but tobacco and hypertension were similar between the groups: men were noticeably more often smoker (p < .0001) and women more hypertensive (p < .005). No difference was noticed for pre-hospital cardiovascular drug treatment. However women were slightly more severe at entry (more Killip class IV; p = .0023; higher GRACE score for in-hospital death - p = .008 and CRUSADE score for bleeding - p < .0001). All the patients underwent PCI of the infarct-related artery after 24 or 48 hrs post admission without sex-related difference either for timing of PCI or primary success rate. During hospitalization, 130 complications were recorded. Though the event rate was slightly higher in women (30% vs. 26% - p = NS), no single event was significantly gender related. The logistic regression identified age and CRP concentration as the only predictive variables in the whole group. After splitting for genders, these parameters were still predictive of events in men. In women however, CRP was the only one with a borderline p value. Conclusions Our study does not support any gender difference for in-hospital adverse events in patients treated invasively for an acute coronary syndrome without ST-segment elevation and elevated troponin.

Abstract
BACKGROUND Sudden cardiac death (SCD) is the predominant cause of mortality in patients with mild heart failure (HF). This 2-year follow-up, multicenter, cohort study aimed to assess the extent to which implantable cardioverter defibrillators (ICDs), by reducing SCD, lead to predominant progressive HF death in mildly symptomatic HF patients at baseline in daily medical practice. METHODS Between June 2001 and June 2003, 1,030 New York Heart Association II patients received an ICD in 22 French centers. Sudden cardiac death and progressive HF mortality rates were assessed using competing risk methodology, and predictors for progressive HF at baseline were tested in a multivariate regression model. RESULTS During a mean follow-up of 22 +/- 6 months, 114 deaths occurred: 12 (10.5%) due to SCD and 52 (45.6%) due to progressive HF (24-month cause-specific mortality rates of 1.2% [95% CI 0.6-1.9] and 5.4% [95% CI 4.0-6.8], respectively). Diuretics use (hazard ratio [HR] 2.8, 95% CI 1.5-5.5, P = .002), history of atrial fibrillation (HR 2.09, 95% CI 1.2-3.65, P = .01), and low ejection fraction (HR 2.7, 95% CI 1.4-4.8, P = .0008) were independent predictors for progressive HF death, whereas beta-blocker therapy was a protector (HR 0.6, 95% CI 0.3-0.9, P = .04). Half of the patients (48%) who died from progressive HF within 2 years of ICD implant initially presented with enlarged QRS (> or =120 milliseconds). CONCLUSIONS Because of ICD efficiency, progressive HF is the main cause of death within 2 years of implant, although these patients are only mildly symptomatic at implantation. In addition to optimal pharmacologic therapy, these results raise the question of systematically implanting ICDs with cardiac resynchronization therapy in patients with electrical asynchronism at baseline.

Abstract
INTRODUCTION Percutaneous coronary intervention (PCI) is widely used actually for the treatment of coronary disease. Stent implantation in the vessel wall is associated with local healing processes and some myonecrosis. However, little is known about the relationships between systemic inflammatory response, myonecrosis and the patient's and procedural characteristics. OBJECTIVES (i) To evaluate the level of C-Reactive Protein (hsCRP) and cardiac troponin I (cTnI) elevation after PCI; (ii) to determine the patient's and procedural factors associated with those elevations. METHOD This is a prospective monocentric study carried out in patients hospitalised for elective PCI or for ACS without cTnI elevation. CRP and cTnI were assessed before, after and 24 hours after the procedure. RESULTS Thirty-four patients (mean age 64+/-10.9 years; sex ratio 28 males/six females) were included. hsCRP increased in 26 patients (76.4%) and cTnI in 16 patients (47%) after PCI. cTnI elevation did not correlate with inflammatory response. Whereas none of the studied parameters were statistically linked with hsCRP increase, cTnI elevation was significantly associated with AHA-ACC B(2)/C type lesion, the number and the total length of stents implanted, the duration of procedure and treatment by betablockers. Multivariate analysis showed that the independent predictors of cTnI elevation were procedure duration (p=0.032 OR=14.2 CI 95% 7.69-100) and the absence of pretreatment with betablockers (p=0.036, OR=2,6 CI 95% 1.35-35). CONCLUSION cTnI elevation following PCI is very frequent and related with the duration of the procedure. Our data suggest a protective role of betablockers in the occurrence of cTnI elevation after PCI. Confirmation of the protective role of betablockers in larger cohort is mandatory.

Abstract
BACKGROUND Early repolarization is a common electrocardiographic finding that is generally considered to be benign. Its potential to cause cardiac arrhythmias has been hypothesized from experimental studies, but it is not known whether there is a clinical association with sudden cardiac arrest. METHODS We reviewed data from 206 case subjects at 22 centers who were resuscitated after cardiac arrest due to idiopathic ventricular fibrillation and assessed the prevalence of electrocardiographic early repolarization. The latter was defined as an elevation of the QRS-ST junction of at least 0.1 mV from baseline in the inferior or lateral lead, manifested as QRS slurring or notching. The control group comprised 412 subjects without heart disease who were matched for age, sex, race, and level of physical activity. Follow-up data that included the results of monitoring with an implantable defibrillator were obtained for all case subjects. RESULTS Early repolarization was more frequent in case subjects with idiopathic ventricular fibrillation than in control subjects (31% vs. 5%, P<0.001). Among case subjects, those with early repolarization were more likely to be male and to have a history of syncope or sudden cardiac arrest during sleep than those without early repolarization. In eight subjects, the origin of ectopy that initiated ventricular arrhythmias was mapped to sites concordant with the localization of repolarization abnormalities. During a mean (+/-SD) follow-up of 61+/-50 months, defibrillator monitoring showed a higher incidence of recurrent ventricular fibrillation in case subjects with a repolarization abnormality than in those without such an abnormality (hazard ratio, 2.1; 95% confidence interval, 1.2 to 3.5; P=0.008). CONCLUSIONS Among patients with a history of idiopathic ventricular fibrillation, there is an increased prevalence of early repolarization.

Abstract
BACKGROUND Early wheezing in infants is a potential risk factor for persistence of asthma into adulthood. Moreover, a personal or familial history of atopy are risk factors associated with persistence of pre-existing wheezing during childhood. However, their relative importance remains unclear. OBJECTIVES Firstly to determine the critical thresholds of common biological markers of atopy in wheezy infants associated with persistence of wheezing into childhood and secondly to rank these biological markers together with clinical parameters according to the strength of their association with wheezing persistence. METHODS A cohort of infants less than 30 months old with recurrent wheezing was established in order to assess severity of respiratory symptoms and to look for the presence of atopy. At the age of 6 years, they were re-evaluated regarding remission of wheezing over the previous 12-months period. RESULTS Data were available for 219 subjects. In 27% of them, wheezing persisted at 6 years of age. Critical biological thresholds associated with the risk of wheezing persistence were: (1) a blood eosinophilia count >or=470/mm(3) (defining eosinophilia), and (2) a total serum IgE level >or=45 IU/mL (defining elevated IgE) during infancy. A multiple component factorial analysis identified a dimension associating eosinophilia, elevated IgE and allergic sensitization on the one hand with persistent wheezing at 6 years of age on the other (lambda=0.15). According to a segmentation analysis, the main discriminative parameter of wheezing persistence was eosinophilia. Thus a lack of eosinophilia alone could account for 91% of infants in remission, and when combined with absence of allergic sensitization, remission was correctly discriminated in 96.9% of the study population. CONCLUSION Our data strongly suggest that the lack of eosinophilia in wheezy infants without ongoing infection could predict future remission of wheezing in a large majority of cases.

Abstract
BACKGROUND Blood transfusion strategies should reduce both blood transfusion and costs. Possible solutions include autologous donation for selected patients and the prescription of erythropoietin (EPO). METHODS We conducted a quality improvement program to examine the effect of a transfusion strategy algorithm in primary knee (TKA) and hip arthroplasty (THA). Our algorithm is presented as a diagram and is based on tolerated and expected blood losses. Patient characteristics, blood loss, transfusions given, autologous blood wastage, and costs were examined during an initial evaluation and after implementation of the algorithm. RESULTS Analysis of 302 (initial evaluation) and 173 (post-implementation) arthroplasties demonstrated a 55% reduction in the prescription of autologous blood donation. The proportion of EPO prescriptions increased from 6.6% to 17.3% (P<0.05). There was a 56% overall reduction in transfusions to fewer autologous (32% vs 12%, P<0.0001) and allogeneic transfusions (21% vs 13%, NS). There were 50% fewer wasted autologous blood units (P=0.002) and a 50% reduction in hospital costs (euro345 vs 169) with no significant change in overall costs (euro439 vs 407). Anaesthetists applied the algorithm in 97% of patients, and it is still in use 1 yr after evaluation. CONCLUSIONS In this study, the implementation of an algorithm for transfusion strategy changed practice and improved quality of care. The costs for EPO, its administration, and monitoring outside hospital were offset by the reduction in hospital transfusion costs.

Abstract
BACKGROUND/OBJECTIVES The extent of microvascular obstruction (MVO) during myocardial infarction referred to as the "no-reflow phenomenon", may determine myocardial damage. Our study aimed to investigate the incidence and the influencing factors of MVO in patients with ST-elevation myocardial infarction (STEMI) treated by primary percutaneous intervention (PCI). PATIENTS, METHODS Using contrast-enhanced MRI, microvascular obstruction was defined as early hypoenhancement. Contrast defects were scored from 0 (no hypoenhancement) to 3 (strong hypoenhancement). 50 patients (56+/-11 years) with STEMI underwent PCI. Contrast-enhanced MRI (6+/-2 days after STEMI) and biochemical parameters were evaluated. RESULTS Microvascular obstruction (score 1 to 3) was observed in 90% of the patients and major microvascular obstruction (score 2-3) in 54%. In univariate analysis, leukocytes and CRP levels were associated with MVO, whereas pre-infarction angina and prior medication by aspirin or calcium channel antagonist appeared protective. Microvascular obstruction intensity positively correlated with baseline inflammation status assessed by C-reactive protein and leukocytes (rho=0.43 and rho=0.44; p=0.003), the peak of CK (rho=0.56; p=0.01) or Troponin I (rho=0.59; p=0.01) and negatively correlated with LVEF (rho=-0.44; p=0.002). Multivariate analysis identified the absence of pre-infarction angina as the only independent predictor for microvascular obstruction (odds ratio, 8.35, 95% confidence interval 1.27-54.71; p=0.027). CONCLUSION MRI-detected microvascular obstruction has a high incidence in patients with STEMI treated by primary PCI and determines post-MI LVEF even in patients with post PCI TIMI 3 flow score. Pre-infarction angina appears to be an independent determinant of the extent of MVO detected by MRI.

Abstract
We have probed the current-phase relation of an atomic contact placed with a tunnel junction in a small superconducting loop. The measurements are in quantitative agreement with the predictions of a resistively shunted SQUID model in which the Josephson coupling of the contact is calculated using the independently determined transmissions of its conduction channels.
